Application filed August 23, 1921.

The object of my inventionis to provide a` steam boiler having .novelmeans provided whereby gas supplied from different sources can be mixedfor producing` a high degree of heat in the lire box.

My invention more particularly .includes a gras generating' meanslocated within the vfire box, the gas fromwhich may be mixed with theordinary city illuminating gas inthe lire box to obtain a' highdegree'of heat.

A practical embodiment of my invention is represented in theaccompanying' drawings, in which Fig. boiler tion.

Float? represents a transverse section taken in the plane of the linell-ll ofFig. 1.

The boiler in connection with which I have illustrated my invention isof the well known horizontal water tube type.v The side walls of theboiler are denoted by 1 Aand 2, thc front wall by 3 and the back wall bye. rThe fire box is denoted by 3 and in lieu of the usual 0rate at thebottom of the lire box l have shown a bottom wall G of .tirebriclr or inlongitudinal vertical cent'al secother lire resisting material. Along'the up-v rising' sides 7 andS ofthis firebox bottom l, l locate twoseries of nozzles 9 and 10 of burners which are connected tohorizontally kdisposed longitudinal pipes 11 and 12 lead-v ing' topressure feeding means, such as rotary lflowers 13 (one only of whichisshown herein). A gas supply .pipe 14 leads from a source of gassupply,such'forinstance as the usual city illuminating' gas supplyttothe pressure feeding'means. y y Y Y These series of nozzles 9 and 10 arepreferably located inthe strips 15 and 16 of extra hard lire resistingmaterial inset into the uprising' sides 7 and 8 of the lire box bottom6. These nozzles 9`and 10 are preferably directed slightly downwardlytoward the said bottom 6 to ensure a complete admixture of the gas fromthis source with the gas from the additional source, the means 1represents my improved steam Specification o f Letters Patent.`l)gi.i;(3n@d Feb, 28, 1922,

for supplying* which will be immediately de scribed.A

Iy locate an additional source of gigas renerating means within the lirebox which means is herein shown as comprising` ascries of horizontallyarranged gas generating' tubes 17 which are supported by and extendthrough the front wall 3 of the boiler into the fire box 57 above thenozzles 9 and 10 of the illuminating; gas burners. These grasgenerating' tubes l? are' lled with diflicultly fusible material 1S inbrolreirup state7 the diflicultly 'fusible material being' preferably ofa gas generating' character such for instance as manganese dioxide whichat a high temperature yields oxygen according to the equation.BMnHgzlllngfl-O2.

Gas pipes 19 lead from the gas generating `tubes 17 to two sefies ofbin-nersthe nozzles 2G. 21 of which extend upwardly through the bottom 6of the lire box. These nozzles are arranged in position to cause acomplete and thorough admixture of the gas issuing therefrom with thegas issuing'A Yfrom the nozzles 9 and 10 of the main sourceofillumihating gassupply.

Steam pipes 22 lead from a source of steam supply into the gasgenerating tubes 17, 'Liquid hydrocarbon supply pipes 213 communicatewith the'steam supply pipes 22 as to beV mixed with the steam when sodesired and forced into the gas generating tubes'l. i i Manuallycontrolled valves 2l are provided for controlling` the admission of 4theliquid hydrocarbon into the steam supply pipes 22. Y

yThere the gas zgenerating tubes 17 are filled with a gas genera-tingmaterial, suchl for instance as an oxygen lgas generating material, asmanganese dioxide,' it may be only necessary to force the steamtherethrough for producing' oxygen gas which can be used to be mixedwith the `gas from the source of 'illuminating' gas supply in the fireboxfto From the above description it will be seen that I have providedeffective means for producing a to be used in combination with the gasfed from the main source of illuminating gas supply in the fire boxwhereby the character of the illuminating gas may be changed tointensify the heat of its products of combustion to a point where it maybe successfully used in steam boiler.

While I have illustrated my invention in connection with a well knowntype of horizontal water tube boiler, it is to be understood that I donot wish to limit myself to that particular type of boiler butcontemplate the application of my invention `to boilers of any typeWhere this invention would be applicable. It is also evident thatvarious changes may beresorted to in the construe tion, form andarrangement ofi-the several parts of my invention without departing fromthe spirit and Scope of the same, hencev I do` not wish to linnt myselfto 'the particu:`

lar embodiment herein shown and described, but

What I claim is l. In a steam boiler, afire box, a source ofilluminating `gas supply, a gas generating device located in the firebox and containing difficult-ly fusible material, means for fe-ed ingsteam and liquid hydrocarbon to said gas generating device, and meansfor leading gas fromboth said sourceofgas supp y and said generating`device into the `lire box for combination therein of theirv products ofvcombustion, f u v 2. In a steam boiler, a lire box, a source ofilluminating gas supply, a gas generating i ply, two other series ofburnersv located in device comprising a series of liorif/.outallarranged tubes located in the fire box and containing diflicultlyfusible material, means for feeding steam and liquid hydrocarbon to saidgas generating device, and means for leading gas from both said sourceof gas supply and said gas generating device into the fire box forcombination tliereinof their products of combustion. y

In a steam boiler, a lire box, a source of illuminating gas supply, agas generating device located in the fire box and containing diiiicultlyfusible gas generating mate ial, means for feeding steam to said gasgenerating device, and means for leading gas from ,both said source oflgas supply and said gas generating device into thefire box forcombination therein of their products of combustion, y

Il. In a steam boiler, a fire box, a source of illuminating gas supply,a gas generating device comprising a series `of horizontally arrangedtubes located in the fire box and containing difiicultly fusiblegasgenerating material, means for feeding steam to said gas generatingdevice, and means for leading gas from both said source of gas supplyand said gas generating device into the fire box for combination thereinof-itheir products' of combustion.
